Surgeon's Knot

By James Castwell

This knot may be used to join two lines or to form a loop; for the loop simply double the standing part and use just one line. It is preferred by many to join tippet to leader. Really an overhand knot with one additional turn, it can be enhanced further by adding yet another, but for most usage it is not needed. Many like it as you can actually tie it without looking at it; you can feel it forming, very useful in the dim light of a spinner fall when you need to change to a new tippet.
